INTRODUCTION
The syllabus is designed to lead to an examination for that part of the school curriculum identified as
Design and Communication. It offers an examination for candidates who have followed a course of
study which centrally figures problem-solving design activity involving practical manipulative work
using a range of materials.
AIMS
The aims of the syllabus are the same for all students. The aims set out below describe the
educational objectives of a course in Design and Communication. They are not listed in order of
priority.
-
To foster awareness, understanding, persistence and expertise in those areas of creative thinking
which can be expressed and developed through investigation and research, planning, designing,
realising and evaluating.
-
To encourage the acquisition of a body of knowledge applicable to solving practical/technological
problems operating through processes of analysis, synthesis and realisation.
-
To stimulate the development of a range of appropriate graphical techniques and processes
including model-making.
-
To stimulate the development of a range of communication skills which are central to design,
realisation and evaluation.
-
To encourage students to relate their practical work to their personal interests and abilities.
-
To promote the development of curiosity, enquiry, initiative, ingenuity, resourcefulness and
discrimination.
-
To offer a broad and balanced perspective of the range of technological applications in order to
provide an understanding of their capabilities and limitations.
-
To encourage technological awareness, foster attitudes of cooperation and social responsibility.
-

CDT: Design and Communication 7048 O Level 2010
NOTES FOR GUIDANCE
In the areas of product analysis and control the most complex items that candidates would be
expected to have experience of would be things such as:
a torch,
a bicycle,
a manually operated camera,
a small pocket radio.
It should be noted that knowledge about specific products will not be required in the terminal
examinations but candidates will be expected to show their ability to analyse products as part of their
project work.
It is not the intention that specific items in the areas listed below should be identified but rather that
examples based on them should be used as a way of teaching and applying the knowledge and skills
developed as a result of studying the core content of the syllabus.
The following lists offer suggestions for areas of study but they should not be considered definitive:
Signs
Symbols and logos
-
-
on control panels
directional
in shops
in streets
on clothes
on instruments and control panels
on maps
on products
on road signs
in vehicles
used by companies and organisations
Packaging – candidates should be familiar with packaging used in ways such as the following:
-
to protect items
to communicate information about a product
to advertise and help sell products
Examples of items to be packaged might include:
-
food
cosmetics
toys
small gift items
small electrical products
records, tapes and CDs
Lines and planes in projection – this area is covered by the sections on auxiliary views and
orthographic projection.

ASSESSMENT CRITERIA FOR PROJECT
This paper presents the candidate with a number of problematic themes. The questions which pose
these problems are open-ended with a low level of directiveness. The candidates should have a good
deal of freedom to determine the length and nature of their involvement with each element required in
this high level design/problem solving process.
(a) Problem identification
The candidates interpretation of the problem presented in a statement,
i.e. the brief
Marks
The candidate has:
failed to identify a suitable problem.
0
either (i) needed help to identify a problem, or (ii) had no help but the resulting
problem is unsuitable for design development.
2
identified and described unaided a problem appropriate for design
development.
5
Maximum marks available in this section:
5
(b) Research and analysis
The orderinq of information relevant to the presentation of a solution
The candidate's research:
consists of copied material, without any evident purpose.
3
has not been initiated independently, or is incapable of forming a planned programme
or the candidate has required considerable assistance and frequent direction.
6
has required significant initial assistance; thereafter little direction has been needed but
the candidate has either concentrated on a narrow area or given only shallow attention to
a wider field.
9
is well planned, broad and imaginative. The candidate has developed a programme
without assistance and this has resulted in information being structured and
effectively communicated.
15
Maximum marks available in this section:
15
7
CDT: Design and Communication 7048 O Level 2010
(c) Specification for a possible solution
The candidate's recognition of those particular factors in research that will determine a
specification for presenting a possible solution.
Marks
The candidate's specification:
is not evident.
0
is very shallow.
2
is vague, not specific to the problem.
4
is not wholly specific, containing some irrelevant material.
6
is specific, but does not completely identify on all the constraints imposed in the problem.
8
is concise, definitive, and is drawn up with obvious reference to the preceding research
and analysis.
10
Maximum marks available in this section:
10
(d) Proposals for a solution
The synthesis and communication of a number of proposals for a solution.
The candidate's response in this area:
is limited to a single unsupported proposal, the communication of which was
largely effective.
5
is limited to a single proposal which is quite well supported and communicated in a
reasonable manner; or a number of largely unsupported and similar proposals
communicated in an uneffective manner.
10
consists of a number of distinct proposals which are unsupported and communicated
in an ineffective manner.
15
consists of a number of distinct well-supported proposals which are communicated in
an effective manner.
20
Maximum marks available in this section:

8
CDT: Design and Communication 7048 O Level 2010
(e) Realisation
The realisation and presentation of a final solution.
Marks
The candidate's solution:
is obviously not a viable solution but is recognisable as an attempt to define a solution.
8
is recognisable as a solution but can easily be faulted in respect of ideas, communication
and quality or because it fails to meet the specification.
16
is incomplete and requires additional material to meet the specification in full, but has
been presented in a form which is easily understood.
24
is substantially free of omission and for the most part fulfils the specification. It has
been presented in a clear, descriptive manner.
32
is well conceived, clearly and attractively defined and fully satisfies the specification.
40
Maximum marks available in this section:
40
(f) Evaluation
Evaluation of the solution, considering the factors raised in (c).
The candidate's evaluation is:
for the most part irrelevant.
2
superficial.
4
an honest attempt to appraise the solution but lacks objectivity providing only
unsupported judgement.
6
almost complete, consisting of some unsupported judgement.
8
thorough, objective, relevant and concise and provides useful material capable of
further development.

External Moderation for Centres in Mauritius
External moderation of internal assessment will be carried out by moderators appointed by the
Mauritius Examinations Syndicate on behalf of CIE. A representative sample will then be sent to CIE
by the Mauritius Examinations Syndicate once in-country moderation is complete.
External Moderation for all other Centres
External moderation of internal assessment will be carried out by CIE.
The internally moderated marks for all candidates must be received at CIE by 31 October for the
November examination. These marks may be submitted either by using MS1 mark sheets or by using
Cameo as described in the Handbook for Centres.
Once CIE has received the marks, CIE will select a sample of candidates whose work should be
submitted for external moderation. CIE will communicate the list of candidates to the Centre, and the
Centre should despatch the coursework of these candidates to CIE immediately. Individual Candidate
Record Cards and Coursework Assessment Summary Forms (copies of which may be found at the
back of this syllabus booklet) must be enclosed with the coursework.
Further information about external moderation may be found in the Handbook for Centres and the
Administrative Guide for Centres.
All records and supporting written work should be retained until after the publication of the
results.
